INVENTOR. 0. Yalwll/e (l. Yannnnr,

residing San county of San Francisco, State iioznia, have inventedcertain new useful improvements in Headlight s; ,o i do declare theIollowmg to be and Lense a full, clear, and exact description of thesame, reference being had to the accompanyinn; drawings, and to thecharacters of reterence marked thereon, which form a part of thisapplication.

This invention relates to improvements in headlight glasses or lenses asthey are more commonly called.

The principal object of the invention is to provide a glass or lens foruse particu-' larly with automobile headlights, to be secured to theheadlight in the usual manner, which while fillOWlIl the full radianceof the light to be thrown onto the ground ahead of .e car, willeffectually keep the glare out of eyes of oncoming drivers orpedestrians, so that they will not be blinded by the glare nowfrequently happens.

A second and very important object of invention is to form aiens orglass which will i'unction as above stated, in such to malts it but veryslightly inary plain lenses. object of the invention is pie anoeexoensive device and "l exceedingly effective hic li is designed.

eans numeral 1 denotes the glass proper, of any suitable diameter orshape of periphery, the

portion adjacent the outer edge as at 2 havmg a thickness adapting it tofit readily into the rim or" a standard form of headlight.

The central portion of the glass however is somewhat thicker, as at 3,this thickness being preferably uniform throughout its extent.

Extending transversely of this center portion throughout its area andfrom front to rear thereof and on a suitable angle sloping For instance,the veins may be formed or molded with the main glass, or if founddesirable the lens may be built up of a number of colored and colorlesspieces of glass, suitably cemented or otherwise secured together in anydesired manner.

No matter how formed or placed however, in the finished product the lensor glass would be a single member, the veins appearing component partsof the g ass, very much hire the ianci'fui COiOILl'V veins orconcentratec neede Fail readily seen that l have produced such a deviceas substantially fulfills the objects of the invention as" set forthherein.

While this specification sets forth in de tail the present and preferredconstruct-ion of the device still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended 10 claim.

Having thus described my invention, What I claim as new and useful anddesire to secure by Letters Patent is p 1,

A headlight lens comprising a single integral clear glass member ofuniform thickness throughout, the same having formed in the integralbody thereof a plurality of equally spaced translucent veins. v I
